As shown in Table 4, after adjusting for age, BMI, baseline T, duration of infertility, and AMH, the high-quality D3 embryo rate was still statistically lower in the IR group for patients with PCOS (adjusted OR: 0.893, 95% CI: 0.816–0.978, p=0.015), and there was no significant difference between the two groups for patients without PCOS (p=0.270). This evidence concerns the gene AMH and Infertility.
